According to NFPA-13, section 5-2 the sprinkler system protection area limitation is 52,000 sq. ft.(ordinary hazard) on each floor, for any one system riser. Is there a limitation on the number of risers in a sprinkler system? What's confusing me is that the flow requirement for a sprinkler system, when determined by the Area/Density method (NFPA-13, section 7-2.3.2.1),is lmited to a maximum value, but there's no limitation I can see on the size of the system, as long as risers are added! Does that mean I can protect an area, regardless of its size, by a limited flow? In other words, is the flow requirement for a one-riser system covering an area of 52,000 sq. ft. the same as the flow requirement for a ten-riser system covering an area of 520,000 sq. ft.?
